SUPPORT AND DRIVING MECHANISM FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 589,995, datedSeptember 1 4, 1897.

I Application filed August 1, 1890. Renewed October 6, 1893. Serial No.487,389. (No model.)

dles and I do hereby declare the following to I be a sufficiently full,clear, and exact description thereof as to enable others skilled in theart to make and use the said invention.

This invention relates to spindles for spinning slivers of fibrousmaterials into yarns,

and has for its object the avoidance of friction in such spindles andthe reduction of wear be- The nature of this invention to effectthesedeslderata consists in a bushing provided with l a shoulder and nutfor holding the same in the rail of a spinning-machine frame, ad'just- 1ing-screws to center the same into alinement with the other parts of thespinningmechanism, a shell or body fitted to screw into the bushing incentral alinement and containing a hollow sleeve upon which the Whirl orpulley turns with devices for avoiding friction and within which thespindle is fitted concen trically, a lower bearing andlubricating-supply and waste-lubricant receptacle, and an equalizing orbalancing carrier for transmiting rotary motion from the whirl to thespindle without imparting any lateral strain thereto.

The construction and operation of this invention are illustrated in theaccompanying drawings, in which-- Figure 1 shows an elevation of thespindle containing this invention asapplied in the rail of aring-spinning machine; Fig. 2, a central vertical sectionthereof; Fig.3, a plan view; Fig. 4, a detached view of the bushing for holding thespindle-support in the frame,

1 represents a portion of the spindle-supporting rail of aspinning-frame; 2, the ring- -rail; 3, the ring; a, the traveler; 5, thecoptube; 6, the spindle; 7, the lower bushing or hearing of the spindle;S,'the step under the bottom end of the spindle; 9, a bushing,preferably of hardened steel, in which the spindle rotates, and 10 awhirl or grooved pulley receiving motion from an endless cord or bandThe whirl 10 rotates around the upper part of the bushing 9 and, asshown in all of the figures of the drawings excepting only Fig. 11, isfitted with two or more series of spherical rollers 12, preferably ofhardened steel, upon which it rolls around the bushing 9 with scarcelyappreciable friction.

The bushing 9 is fitted into a bearing formed within and concentric withthe axis of a tube 13, closed at the lower end, fitting exactly with ascrew-thread 14c into a corresponding screw-thread in the interior of abushing 15, and secured by a nut 16 in the bearingrail 1 of thespinning-frame.

The tube 13 is provided with a shoulder 17, which fits against the undersurface of the bushing 15, the parts being so fitted or finished thatthe tube 13 isalways,whe1 1 screwed tightly into the bushing l5,coincidentin axis therewith. p

The bushings 15 are of sufficiently less diameter than the openings inthe ring-rail in which they are placed as to permit of adjustment toline them concentrically with the rings 3 in the ring-rail 2.

In order to facilitate the centering of the rupting the working ofcontiguous spindles and without waiting for the ring-rail 2 to reach theupper end of its stroke.

Upon the upper side of the whirl 10 are formed two diametricallyopposite projections 30,which engage in slots 31 in a plate 18, havingtwo other slots 19 at right angles thereto, each of which engages one oftwo projections 20, diametrically opposite to each other, secured to thespindle 6 and transmitting the rotary motion from the whirl 10 throughthe projections 30, slotted plate 18, and projections 20 to the spindle6.

The whirl 10 is supported upon the outer surface of the bushing f) andhas no other connection with the spindle than through the slotted plate18.

The slots in the plate 18 permit a sliding motion of the projections 30and 20 in directions at right angles to each other, so that equal forceis transmitted upon opposite sides of the spindle 6, and the spindle isthus protected from the effects of any concussions upon the whirl 10from inequality of the driving-bands.

In the form shown in Fig. 12 a fork 32, fitting pivotally through thespindle with prongs 33 turned downward, engages in opposite radial slots31 in the Whirl 10, and in the form shown in Fig. 13 a tube 35,connected pivotally by gimbal-rings 36 and 37 to the spindle andwhirl,respectively,transinits rotative motion from the whirl to thespindle without transmitting any vibratory motion between the parts. Theballs 12 roll between the inner surfaces of the whirl 10 and the outersurfaces of the bushing 9, so that a minimum of friction is preserved.The balls 12 are kept in their proper planes of rotation by a collar 22and shoulder 21, formed in the whirl 10, and a like shoulder upon thebushing 9. (See Fig. In this form the weight of the whirl and thedownward pressure resulting from the strain of the driving-band 23 aresustained by the balls 12 between the shoulder 21 and the shoulder ofthe said bushing, avoiding the friction otherwise incident to surfacesmov ing in sliding contact with each other.

As shown in Figs. 12 and 13, there are several series of ballsinterposed between the bushing 0 and whirl 10. It should be observedthat the lower series of balls 12, which support the weight of the whirl10 and the downward thrust or draft of the drivingband 23, do not touchthe cylindric surface of the bushing, but are free to roll with thevelocity acquired from the shoulder 21 on the whirl 10.

In Fig. 11 of the drawings is shown a form of this invention, in whichthe whirl 10 is fitted directly upon the bushing 9, and consequentlyrequires lubrication more frequently. 0n the lower part of the whirl 10there is formed a rim 21, having its greatest external diameter at thelower edge. The function of the rim 24: is to convey any surplus oilfrom the whirl 10 downwardly within a surrounding rim 25, formed on theupper end of the tube 13, in which rim 25 such oil is whirled from therim 21 and collected, whence it is conducted downwardly, as hereinafterdescribed, and utilized in lubricating the lower wearing parts. The tube13 is bored out accurately in line with the axis of the screwed portionand exactly true with the shoulder 17, so that the bushing, 9 andbearing 7 and step 8 are always accurately in line. Chambers 26 areformed between the bearings of the bushings 9 and bearing '7 and step 8,and channels 31 are cut lengthwise through these bearings to permit oilto flow down from the top to lubricate them and to flow below the step 8and deposit any sediment or heavier foreign substances in the oil belowthe bearin g-surfaces, thus protecting the wearing parts from injury andaffording a space for the subsidence of the oil after its lubricatingproperties are exhausted or impaired. A spring-plate 28, attached byscrews 38 (shown in Fig. 3) to the bushing 15, projects over the whirl10 and serves to prevent the whirl 10 and spindle 6 being accidentallylifted from the bearing,and by being pressed downwardly at the free endinto contact with the whirl 10 serves as a brake to arrest its rotation.

To remove any of the spindles and bearings, it is merely requisite tounscrew them from the bushing 15 and withdraw them downwardly, which canbe done with the ring-bearing rail in any position and without the leastinterference with the work of contiguous spindles. A cap 27 serves tocover and protect the carrier and whirl from dust.

I am aware that spinning-spindles have been made elastically connectedwith driving-whirls, and that spinning-spindles connected by frictionalsurfaces with their driving-whirls have been used also, thatspinning-spindles supported to gyrate upon axes other than that of theirgeometric form have been connected with their driving-whirls by across-pin passing through the spindle loosely and secured in the whirl,none of which devices do I claim; but,

Having described my invention, what I claim is 1.
